WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 372,877, dated November 8, 1887,

Application filed April 22, 1887. Serial No. 235.810. (No model.)

I Wellsville, in the county of Allegany, and the State of New York,have invented a new and Improved Washing-Machine, of which the following is a full, clear, and exact description.

This invention relates to an improvement upon that form ofwashing-machinethatisiliustrated, described, and claimed in Letters Patent No. 133,389, granted tome on the 26th day of November, 1872, the object of the present invention being to provide areversible rollerdepressing spring.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is aside view of my improved form of washihg-machine, parts being broken away and the machine being shown as it appears when arranged in connection with a tub, the tub shown in the drawings being represented in section. Fig. 2 is an end view of the machine. Fig. 3 is a view of one of the links employed to connect the outer ends of the springs.

, Fig. 4 isa side view ofsaid link. Fig. 5 is a Y cross-sectional view taken on line w as of Fig.

1, and Fig. 6 is a cross-sectional view taken on line y y of Fig. 1.-

In the drawings above referred to, 10 represents the frame of the machine, in which frame there are mounted two rollers, over which there is passed a belt, 11, a pressureroller, 12, being arranged as shown. This construction is old, and is fully shown in my former patent. The gudgeons 2 of the pressureroller .12 are mounted in vertical slots 3, that are formed in the side bars of the frame 10, and above these gudgeons I arrange blocks 13, the main bodies of which fit within slots 3, each block being formed with a side rib or flange, 4, as illustrated, said flanges or ribs being held against the outer faces of the sides of the frame 10 by metallic boxes 14, which are secured to the frame.

In order that the pressure-ro1ler 12 may be held to the lower rollers, over which the belt 11v passes, by a yielding pressure, I provide a compound spring consisting of four tapering spring-bars, as 16, 17, 18, and 19, the ends of the bars 16 resting upon the blocks 13, while the bar 17 is supported by a double metallic clip, 20, that is made in two sections, 5 and 6, as best shown in Fig. 5, the two sections being each formed with two half-sockets and a central web, the arrangement being such that when the two sections are brought together and united by a bolt or screw, 7, the rods having been previously inserted within the sock etsat each side of the webs, the rodsv will be held apart and in the position in which they are shown in Fig. l. Recesses 8 are" formed as illustrated, said recesses being adapted to receive pins 9, that are carried by the rods or bars 16 and 17. A second clip, 20, is arranged in connection with the spring bars or rods 18 and 19, and the ends of the bars 17 and 18 are connected by links 21, the construction of which links is clearly shown in Figs. 3 and 4.

Io each of the side pieces of the frame 10 I connect a bail, 22, which bails may be turned to the position shown in dotted lines in Fig. 1, in order to free the compound spring from engagement with the frame; but when the bails are turned up to their normal position, as illustrated in the drawings, they will overlap the ends of the springbar 19 and hold them in position, the parts being so proportioned that when the compound spring is placed in position the blocks 13 will be forced down hard against the gudgeons of the roller 12.

By providing such a spring as the one described I am able to give each of the bars a half-turn in its socket, thus avoiding the danger of the bars becoming set at any particular curve, which might happen if no provision were made for turning or reversing; and by providing the outer boxes or casings, 14, for the blocks-13I arrange for more surface wear of the blocks and prevent all wabbling of the gudgeons in their bearings.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A compound spring for washing-ma chines, consisting of two pairs of spring-bars centrally connected by clips, the ends of the approaching bars being connected by links, substantially as described.

2. A compound spring for washing machines, consisting of four spring-bars detachably connected together at the center in pairs,

the adjacent bars of the pairs being connected together, substantially as herein shown and described.

3. The herein-described spring for washing- 5 machines, consisting of the bars 16, 17, 18. and

and the links 21, connecting the ends of the bars 17 and 18, substantially as herein shown and described.
